Odd Feeling

So I’m having this weird feeling...My body got hot all of a sudden and I feel like I’m in a bit of a “doom” or “panic” mode. I’m laying in one place of the bed but I feel terrified. I feel like when I look around/move it feels so foreign to me or something idk I just can’t put my finger on what it is or how to describe it properly. Feel a bit stiff in my arms and body etc. I always have this feeling that I should be having “more of an experience” in everything I do. It’s weird to me that we can type/read/walk etc mindlessly without really being there and experiencing it. Idk I just feel so odd and it is scaring me. What is this feeling? 😩
